Abstract

The invention relates to the field of chain arm saws, in particular to a speed reducer of a chain arm saw. The speed reducer comprises a machine box, a transmission shaft assembly, and worm and gear assemblies; the worm and gear assemblies are fixed on the inner wall of the machine box; the transmission shaft assembly is connected with the worm and gear assemblies; the transmission shaft assembly is driven by the worm and gear assemblies to move; each worm and gear assembly comprises a main worm, a main worm gear, an auxiliary worm, and an auxiliary worm gear; the two ends of the main worms are fixed to the inner wall of the machine box through connecting parts; the two ends of the auxiliary worms are fixed to the inner wall of the machine box through connecting parts; the main worms are tangent to the main worm gears; the auxiliary worms are tangent to the auxiliary worm gears; the auxiliary worms are tangent to the main worm gears; the main worms and the auxiliary worms form angles of 90 degrees; and the main worm gears and the auxiliary worm gears form angles of 90 degrees. Due to the fact that the two worm and gear assemblies which are perpendicular to each other and are in linkage are arranged in the speed reducer of the chain saw arm, the cutting speed and the cutting angle of a chain arm of the chain saw arm during operation are effectively controlled, and the accurate cutting of stone is achieved.

Description

technical field [0001] The invention relates to the field of chain arm saws, in particular to a reducer for chain arm saws. Background technique [0002] As an efficient stone processing machine, the chain arm saw can effectively avoid the collapse of the mountain and ensure the safety of the workers. When cutting stone with a chain arm saw, it is necessary to accurately grasp the cutting speed and angle in order to cut out the appropriate size. [0003] However, when the chain arm saw is used for stone cutting, the long chain arm of the chain arm saw is not easy to control, resulting in a low yield rate of the cut stone, which cannot meet the requirements of precise stone processing. Contents of the invention [0004] The object of the present invention is to provide a reducer for a chain saw to solve the above technical problems. [0005] The technical problem solved by the present invention can adopt following technical scheme to realize: [0006] A reducer for a cha...
